Implements several changes to the transport layer segmented tx to
improve group message performance:
- Moves retransmit counter to tx context instead of per packet. As every
unacked packet is sent every retransmit, the retransmit counters would
be the same in each segment. This makes it easier to control progress.
- Delays the scheduling of the retransmit until the completion of the
last segment by adding a seg_pending counter. This is essentially the
same as the old behavior, except that the old behavior might retrigger
the sending before all segments are finished if the advertising is
slow.
- Allows the group transmits to stop as soon as all retransmits have
been exhausted, instead of timing out waiting for acks that won't
come. This allows group tx to finish without error.
- Fixes a bug where a failed TX would block IV update.
- Cancels any pending transmissions of acked segments.
- Reduces log level for several common group tx scenarios that aren't
erronous.
Using the ble mesh white list test functions, a node can choose to
only receive mesh messages from a specific node and relay the
messages for it. Messages from other nodes will be ignored.

Stores friend queue packets unencrypted, removing any out-of-order
issues caused by seqnum allocation. Also moves as much of the metadata
storage as possible into the packet, allowing us to free up some bytes
of net_buf user data for friend packets.
